  eco hydrological
The eco-hydrological model SWAT investigates the effects of these land use options on the water balance and water related nutrient fluxes.
      
Details aside, the analytical model thus seems to capture the essentials of the physics of the underlying eco-hydrological processes.
      


A new equation for calculating the transpiration and evaporation by means of Eagleson stochastic dynamic water balance model is presented in this paper. In the model, the influence of limited water supply to the plant is considered and the raining season within a year is divided into 16 periods, according to the characteristics of the rainfall in loess region. The mass conservation equation and a prediction correction algorithm by means of step by step are applied to calculate the partitioning of the water...

A new equation for calculating the transpiration and evaporation by means of Eagleson stochastic dynamic water balance model is presented in this paper. In the model, the influence of limited water supply to the plant is considered and the raining season within a year is divided into 16 periods, according to the characteristics of the rainfall in loess region. The mass conservation equation and a prediction correction algorithm by means of step by step are applied to calculate the partitioning of the water balance factor and the average soil moisture in the 16 periods within a year. All these improvement elevates the calculation accuracy of the model and makes it more useful, especially for water balance modeling of eco hydrological system in the loess plateau.

The research results of "Forest and Water"in the XXI IUFRO World Congress was reviewed from the aspects of eco hydrological function of forest, effects of forestry activities on soil erosion and slope stability, the application of high and new technology in forest hydrological research and the eco hydrological models and simulation of forest ecosystem. From the viewpoint of forest ecosystem and combining with the research on forest structure, function, productivity and energy and material circulation,to explore the laws and internal relations of various forest hydrological phenomenon is the basic topic of research. The priorities towards 21st century about forest and water are as below:(1)effects of forest vegetation on water balance and soil erosion and their scaling;(2)forest watershed and ecosystem management;(3)the application of new remote sensing and stable isotopes technologies on forest hydrological research;(4)eco hydrological models and simulation technology of modern forest hydrology.

Hulun lake is a typical lake characteristic of grassland. Being less affected by the human being, the water environmental system of Hulun lake is strongly affected by the eco hydrological process of the basin. Under the condition of global change and irrational action of human being, the water environmental system is being deteriorating. The control of water environmental system must be on the base of the control of eco hydrological process of the basin.
